I came here via train on a late Sunday afternoon in early December 2022. The train station dropped you off at the far north of the garden. Let me tell you - be prepared to get very lost if it's your first time there. This place is huge!
It Is right next to the National University of Singapore. I kept stumbling into the University and having to make my way back into the Garden. There are a lot of people having picnics, taking photos of the birds/plants, exercising, walking their dogs - you name it! It was 88 degrees Fahrenheit and super humid - I, along with all the dogs I came across, were dying.
I couldn't make it much farther than the Corner House restaurant, which was the main reason I was there since I had reservations. Throughout the garden there were sprinkles of little museums here and there that were open to the public. They were amazing because they all had air conditioning and restrooms. If you need something to do to kill time, this is definitely the place to do it. You can easily spend 2 or 3 hours here. Even though the roads are all paved, make sure you bring your comfortable walking shoes.
